a reclining bed that raises the upper body and legs above horizontal, but also allows the legs to recline below, the horizontal position. The resulting ergonomic benefits of sitting up for extended periods of time makes the desk specifically designed for such a bed a necessity.

A chair that has movable thigh levers to permit a shifting of body weight when seated and thereby relieve spinal discomfort and pressure points experienced when seated for long periods. A lever support rocker is provided to coordinate movement of the thigh levers. Downward pressure exerted by a user's thigh to lower a first thigh activated lever causes a rocking movement of the lever support rocker which results in an upwardly movement of a second thigh activated lever.

A rehabilitation training and exercise chair where the user can sit comfortably for long periods of time is provided. The chair is comprised of a base having wheels and is coupled to a shaft on one end. The shaft is coupled to a seat on its top end. The seat has an adjustable inclination so the correct ergonomics may be realized for the pelvis and lower spine. A front support bar with an adjustable length is connected to the seat and can be pivoted back or forward. The front support bar has a cushioned front support which rests against a user's abdomen. Furthermore, abductor and adductor extensions are attached to the seat, and foot extensions attached to the base for isometric exercises.

A seat structure which can ameliorate fatigue of a sitting person in accordance with a long period of sitting is provided.In a vehicle seat 10, a back edge side of a lower layer sheet 50 of a cushion material 20, of which a front edge side is fixed to a front edge side of a sitting portion frame 14, is resiliently connected to a back edge side of the sitting portion frame 14 via a movable frame 34 and a torsion bar 46, which is a resilient member. The cushion material 20 has a spring zero characteristic in which a spring constant of a portion that supports a protrusion portion of the sitting person is smaller than a spring constant of other portions. This vehicle seat 10 makes smaller the energy of vibrations which are transmitted to a spinal column portion of the sitting person through the sitting portion frame 14, and peripheral portions thereof convert vibrations corresponding to fluctuations in the body and transmit these through the sitting portion frame 14. α waves of 10 Hz to 12 Hz, which occur in a relaxed waking state, are caused in the brain of the sitting person. Vibrations in a resonance frequency region are attenuated in amplitude and transmitted to the sitting person.

A pad for supporting a thigh of a person sitting on a seat in a position that alleviates pressure applied to the lower surface of the thigh and thus for improving blood circulation through the leg without numbness or similar phenomena associated with long-time sitting. The pad is made in the form of a soft deformable body filled, e.g., with a silicone gel. The pad has a flat rectangular bottom surface and curvilinear lateral sides. In the plane perpendicular to the bottom, the pad has a triangular cross-section with heights of the triangles gradually reduced from one end face of the pad to the opposite end face of the pad so that the ridge that connects the apexes of the triangular cross-sections from one end face to the other is inclined with respect to the flat bottom.

The present invention includes an ergonomic chair that is useful for people who sit for an extended period of time at work, in avoiding work station related back pain and neck pain. The present invention incorporates a hemispherical seat which can be locked in position and comprises a fixed inner hemisphere, a movable outer hemisphere, and a shroud. The support pole where the inner hemisphere is bolted into absorbs the load from the user, and the outer hemisphere equipped with hydraulic or pneumatic resistance devices and attached to the tension springs provides a balanced movement of the chair. Accordingly, while sitting on the chair, the present invention allows no deformation on the rigid hemispherical seat, and keeps the spine of the user in a desirable alignment, further improving the internal function of the user's organs. The present invention can also be used as an office stretch GYM ball.

A portable harness that wraps around the rib cage and thoracic spine is disclosed. Unlike other harnesses, the present invention has an extension allowing it to be suspended above the user's ribcage to apply an upward pull. This suspension strap provides a distracting / unloading force on the lower back by holding the upper torso in place while the weight of a patient's lower body creates traction on the lumbar spine. The harness can be used with any chair back, including office chairs, or vehicle seats. This allows people with lower back pain to sit more comfortably while sitting in a regular chair, driving a car, or flying in a plane. This will decrease low back pain since sitting for long periods will no longer compress the lumbar spine, it will actually be therapeutic by allowing a person to sit in an unloaded position.

A mobile body unweighted sit and stand chair assembly prevents repetitive stress from sitting, standing, and lifting objects for long periods. The assembly provides a vertically, rotatably, and pivotally adjustable seat, a restrictive support padding that rotates from a support bracket to selectively support the spine or the pelvis, and a frame for structural integrity, mobility, and steering. The seat supports the buttocks and the ischium region of the pelvis, tilting forward up to 35 degrees to abut the pelvis against the support padding. This forward position maintains the spine in a straight posture and forces open posterior intervertebral disc space. The seat is supported by an adjustable rod that supports the weight of user while sitting, walking, kneeling, or lifting. A frame includes wheels that enable mobility and a brake. A first bracket enables feet to steer for hands-free maneuverability. A second bracket provides balance during kneeling and lifting.
